  • Such an indication of the actual opening or closing condition of the centralized lock provided on the motor vehicle door opening/closing telecontrol device allows to practically remove any doubt of the user related to the last sent command, respectively to an effective implementation of the latter, which cannot be always safely detected, for example because of a nearly exhausted condition of the telecontrol device battery, or because of a comparatively large distance of the vehicle, as well as due to obstacles, or a doubt related to an actually pressed push-button of the telecontrol device, and so on.
  • the implementation means for confirming the current opening or closing condition may be easily built-in both in the telecontrol device and in the central unit or station of the vehicle, without remarkably increasing their size or occupied space.
  • the telecontrol device can comprise, for example, three push-buttons, two whereof for performing a conventional opening and closing function, and the other for performing an interrogation function, to be carried out by the user, related to the current condition of the centralized lock, and preferably two differently colored LED's, for example a red LED and a green LED, to provide display functions related to the respective closing or opening condition.
